ATQMIZER.

SPECIFICATION forming' part of Letters Patent No. 757,157, dated April 12, 1904.

Application iiled June 26, 1902. Serial No. 113,195. (No model.)

, citizen of the United States, and a resident of ing a sliding engagement with the bulb and Winthrop, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Atomizers, of which the following is a specification.

My invention relates to atomizers; and its object is to produce an atomizer which shall be collapsible, and therefore convenient for transportation, of few parts, simple and effective `in construction, and adapted to be oprated by one hand, leaving the other hand ree.

My atomizer employs a bulb of usual type common in all atomizers and a receptacle havcapable of being pushed within the bulb and withdrawn from it in telescoping fashion, still remaining in engagement therewith, as shown in the patent' to C. J. Seltzer, No. 700,838, datedl May 27, 1902.

A11 em bodiment of my invention is illustrated in the accompanying drawings, in which Figure 1 is a central longitudinal section of the bulb, showing the receptacle in elevation and the atomizer in telescoped orA contracted position. Fig. 2 is a central longitudinal section, enlarged, of the receptacle and parts located therein. Fig. 3 is a cross-section through line 3 3 of Fig. 2. Fig. 4 is a much enlarged elevation of the air-nozzle, and Fig. 5 is a plan view of Fig. 4.

A representsthe bulb, and B an air-inlet check-valve of ordinary construction inserted at the free end of the bulb. At the end of the bulb opposite the cheek-valve B is a mouth or aperture, within which is secured a ring C, of hard rubber, metal, or. other suitable material, to which the edges of the mouth of the bulb are secured. The telescoping receptacle D is fitted within this ring C and has a sliding engagement therewith. the receptacle l), is slightly conical in form, as shown .at D, the effect of which is that a wedge-union and fluid-tight joint is formed when the receptacle is drawn out between the ring C and the receptacle. Fitted to the outer The inner end. of`

end of the receptacle D is a screw-cap E, having a nozzle F of any suitable form exteriorly, the end of which is provided with a smalldischarge-orifice G, through which the atomized liquid is discharged. Within the receptacle andeommunieating through the bottom of the receptacle with the interior of the bulb A is an air pipe J, the upper end of which is conical in orm and its within a conical seat on the inner surface of the cap E., which centers the pointof the pipe J so that it registersl with the discharge-orifice G. In the preferred form of my device shown in .the drawings a liquid-pipe H depends from the cap E into the receptacle, iuclosingthe air-pipe J (see-Fig. 3) and extending nearly to the bottom of the receptacle. The conical nozzle vA of the airpipe J is provided with grooves le and has an air-opening L. The grooves le form ducts for the passage of the liquid from the liquid-tube through the orifice Gr. A minute air-inlet e is provided in the screw-cap E or at any suitable point in the walls of the receptacle D, communicating with the air-space within the' receptacle for the purpose of admitting air to replace the liquid which is drawn out of the receptacle by the operation of the device, and this inlet may be made as small as possible in order to avoid any leakage of the liquid contents of the receptacle.

The operationl of my improved atomizer is as follows: The teleseoping receptacle D is pulled out until the conical end D' of the receptaele engages'the lower end of ring C and by its wedging action forms a fluid-tight and union joint between the rec'eptacle and the ring C. This is a feature of some importance in a telescoping atomizer, since the escape of air by any other outlet than the proper airpassage J would seriously impair the etliciency of a device like that shown, in which the lift- `ing of the fluid is entirely accomplished by vacuum-suction as distinguished from the mode of operation which is shown 1n the Seltzer patent above mentioned, 1n vwhich the Xliquid is elevated by direct pressure of the compressed air upon the surfaceof theliquid. When the bulb A is collapsed by handfthe I5 l sure and in rapid motion.

air within isvcompressed and forced upward through the air-tube J, escaping through the .orilice Gr. In doing this -the air within the liquid-pipe H is drawn upward, .creatinga partial vacuum,.which is relieved by tline'rising'oi the liquid from below. =It will be^observed that the air-space within the liquid-pipe is of comparatively small area. The result is that the operation of my device is veryprompt.

It will be observed also, that the `liquid in its discharge is arranged around the rapidlymoving column of compressed air, so that when the liquid' and air issue through the oriice G .the effect is as of a hollow cylinder of liquid lled with a column of air under pres- The effect is that as soon as the hollow column of liquid illed with compressed air, as above described, passes y tained are due to this arrangement and organied and the liquid rises.

zation of parts. The results may be summarized as follows: prompt action, whereby as" soon as the air begins topass under pressure, through the air-pipe ther very small air-chamber at the upper end of the pipe H is exhaust- This arrangementv and proportioning of the parts also results ina great efficiency and continuity of operation, the liquid rising quickly and continuing to rise almost as long as the air continuesl to move upward in the air-pipe J. The concentric arrangement of the pipes also, as has Ybeen pointed out, places the air under pressure within the hollow column of water, so that as soon as the column of air and water is free from the restraining-walls of the cap E the air expands in alll directions, finely comminuting the water in all directions, since the Water. is without the "air, and the air will instantly expand in all directions.

When the atomizer is not in use, the receptacle D may be pushed Within the bulb A, as shown in Fig. 1, and the cap M may be placed l' y over the nozzle F to prevent the escape'o'fthe 1 liquid.

-I claimi y 1. An atomizer comprising a bulb; a receptacle to which the bulb is fastened madein two separable. partsA detachably fastened to;

gether, .and with a discharge-orifice through.4

one end; a pair of tubes within the receptacle comprising an inner tube fixed at one end to one of the two .parts of the receptacle and commu-y nicating at that end with the interior of the bulb, the other end of said inner'tube registering with the discharge-orifice ofthe receptacle; and an outer tube surrounding the inner tube held at one end by the other part of the receptacle and communicatingat that end-With the discharge-orifice and at its other end with the interior of the receptacle.

2. An atomizer comprising a bul-b; a receptacle arranged within the mouth of the bulb made 4in two separable parts detachably'fastened together, and with a discharge-orifice at one end; an inner tube within the receptacle fixed to onepart thereof, one end of the inner tube registering with thedischarge-oritice and the other end-communicating through the end of the receptacle with the interior of the bulb; an-'outer tube surrounding the inl ner tube held at one 'end by the other part of the receptacle and communicating at that en d with the discharge-orifice and at its otherend with the receptacle,l and an air passageway communicating with the receptacle adapted to admit air to compensate for liquid removed therefrom. f

, 3. In an atomizer, in combination, a b ulbV `and'a liquid-receptacle, the latter arranged to slide telescopically Within the mouth of the bulb, theinner end of said receptacle vbeing made `with an exterior tapering enlargement for limiting the outward movement of the receptacle, and adapted to` be wedged into the mouth of the bulb to prevent leakage between the receptacle and bulb.
